Baydiff: Bayesian diffusion chronometry for volcanic systems
Diffusion chronometry is a powerful tool for estimating the time scales of magmatic processes. This MATLAB software can be used to estimate diffusion time scales using the forsterite content of olivine crystals. Estimates are obtained probabilistically, using a Bayesian framework, and account for uncertainties in data as well as any independent (prior) information.
North American Breeding Bird Survey (BBS) stop-level uncertainty code
The North American Breeding Bird Survey (BBS) (https://www.pwrc.usgs.gov/bbs/) has counted birds annually for over fifty year. Survey 'routes' each consist of 50 'stops' (counts) placed along a line. Inter-stop distances can vary from route to route and from year to year, and precise locations of each stop are not typically recorded.
This script quantifies uncertainty in BBS stop locations using d
Scaling Landsat Collection 2 Level 1 Data
In this tutorial, we will use London, England, one of the brightest cities on Earth, to show users how to convert provided Level-1 Radiance products to TOA Radiance, Reflectance, and Brightness for the area. The tutorial will also show how to pull and parse the metadata file (MTL file) for a Landsat scene; the MTL file is used to obtain the necessary parameters for calculating Radiance, Reflectanc
Introduction to Landsat Cloud Access Direct Requester Pays
This tutorial demonstrates how users can access Landsat data stored within the AWS Cloud environment using basic commands. Landsat data stored in the AWS Cloud is located within the U.S. West (Oregon) us-west-2 region in a Requester Pays Simple Storage Services (S3) bucket. Users interested in utilizing direct access to Landsat data stored in S3 are encouraged to visit the Requester Pays Documenta
North American Bat Monitoring Program: R Data Connection Package (Version 1.1.0)
The North American Bat Monitoring Program: R Data Connection Package can be used to extract and upload data to the NABat Monitoring Program through the GQL API. This software is written as a wrapper around the NABat GQL API. Documentation for the database and API can be found at https://sciencebase.usgs.gov/. This code includes the ability to reformat NABat data, upload NABat data, create reports,
ModelMuse: A Graphical User Interface for Groundwater Models
ModelMuse is a graphical user interface (GUI) for the U.S. Geological Survey (USGS) models MODFLOW 6, MODFLOW–2005, MODFLOW-LGR, MODFLOW-LGR2, MODFLOW-NWT, MODFLOW-CFP, MODFLOW-OWHM versions 1 and 2, MODPATH, ZONEBUDGET, PHAST, SUTRA 2.2, SUTRA 3.0, SUTRA 4.0, MT3D-USGS, and WellFootprint and the non-USGS programs MT3DMS and PEST.
syntheticdv2lff, Scripts for low-flow frequency (LFF) estimation (and bias correction) from daily mean streamflow estimated at level-12 hydrologic unit code (HUC12) pour points in the southeastern United States
The syntheticdv2lff repository contains R language source code that document the workflow to compute low-streamflow (low-flow) frequency (LFF) statistics from previously estimated streamflow at level-12 hydrologic unit code (HUC12) pour points (watershed outlet locations) in the south-central and southeastern United States for 1950 through 2010 and associated bias correction. LFF statistics comput
WRTDSplus: Extensions to the WRTDS method.
For some sites and constituents the three dimensions of the Weighted Regressions on Time, Discharge, and Season (WRTDS) model do not capture all the important aspects of water quality variability. For example, in some locations hysteresis or antecedent flow conditions are important influences on water quality concentration and loads. In other places, daily flow is less predictive than the quick fl
MapMark4 Version Update (Version 1.1)
MapMark4 is a software package originally released by Ellefsen (2017) that implements the probability calculations in three-part mineral resource assessments (Singer and Menzie, 2010). The name is derived from the descriptive phrase “mineral assessment program mark4”—the name “mark4” is chosen because the previous, similar program was called “mark3”. Functions within the software package are writt
Landscape transcriptomic analysis detects thermal stress responses and potential adaptive variation in wild brook trout during successive heatwaves
Extreme weather events, such as heatwaves, are becoming more frequent and intense as a result of climate change. Importantly, such extreme weather events can be more important drivers of extirpation and selection than changes in annual or seasonal averages and they pose a particularly large threat to poikilothermic organisms. In this study, we evaluate the thermal stress response of a coldwater ad
pfdf 2.0.0
This release substantially improves support for working with datasets in a mix of coordinate reference systems. The release also introduces new classes for working with spatial metadata, adds confidence intervals to the Gartner 2014 volume model, adds support for additional unit systems, and improves the user experience when filtering the stream segments in a network.
grsg_lekdb: Compiling and standardizing greater sage-grouse lek databases (version 1.3.0)
Greater sage-grouse (Centrocercus urophasianus; hereafter referred to as sage-grouse) are landscape-scale sagebrush obligate species and an important gamebird and iconic species of the West (Hanser & Knick, 2011; Rowland et al., 2006). They occupy the sagebrush biome in western North America, extending east of the Sierra Nevada/Cascade Mountain ranges to the western regions of the Great Plains of
